The study aims at diagnosing current state of research on Korean intonation for teaching KFL and teaching materials for both KFL teachers and learners and providing implications for teaching intonation. For this, the study, first, categorizes the functions of Korean intonation into four: grammatical function, attitudinal/affective function, discourse function, and sociolinguistic function. The study examines the previous research on interlanguage intonation of Korean, comparative studies between Korean and other languages, and the research on teaching Korean intonation in terms of the four functions. The study also analyzes four introductory textbooks on teaching pronunciation for KFL teachers and two KFL textbooks for the learners. The study, finally, reveals that disparities across the functions in both research areas and teaching materials, and proposes some implications for teaching Korean intonation to KFL learners.
